As reported by the Des Moines Register, Warren Buffett's MidAmerican Energy has finally pulled the plug on a proposed new "small modular reactor" it was hoping that the ratepayers of Iowa would pay for, through "Construction Work in Progress" (CWIP) surcharges on their electricity bills. A powerful coalition, including AARP, Green State Solutions, Sierra Club, Friends of the Earth, and others can claim credit for this environmental victory against nuclear industry greed, after a protracted three year long battle at the Iowa state legislature.
